HORSESHOE.

SPECIFICATION, forming part of Letters Patent No. 329,141, dated. October 27, 1885.

Application filed December 23, 1884. Serial No.151,042. (No model.)

. To all whom it may concern.-

Be it'known that I, LOUIS G. CLAUDE, a citizen of the United. States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to machine-made 'horseshoes, and has special reference to those made of combined iron and steel with solid calks.

Figure l of the accompanying drawings is a plan of the upper side of my improved horseshoes designate steel, and the dark portions,

shaded with a tint of ruled lines, designate lIOH.

I will first describe in detail the shoe shown in Figs. 1 to 4. The body of the shoe is a fiat plate, A, of the curved outline shown, and integral with it are the toe-calks B and heelcalks O O. The grain or fiber of the metal extends in a straight or parallel direction longitudinally of the shoe, and consequently crossing its toe portion in a direction substantially transverse to the outline thereof. At this portion, which is the only part of the shoe where the grain of the metal crosses it transversely, the shoe is thickened by the toe-call:

B, which extends across the toe transversely to the grain of the metal, and is preferably elongated laterally of the shoe, as shown. Through the middle of the toe and toe-call: passes a stripe or streak, a, of iron, and on each side of this and parallel with it are two streaks or cores, b b, of steel, which extend from the front edge of the shoe across the toe portion and down each leg, on the inner side thereof, to the heel. Outside of these steel portions are flanks c c of iron, which extend along the outer'sides of the shoe to the heels. The toecalk B extends across the iron center a, and its ends are formed of the steel portions 1) b. The heel-calks O O are formed mainly of the steel portions 11 b, and the outer side of each ulation.

is formed of the iron portions 0 0. At the eX- treme toe of the shoe the usual toe-clip, D, ex-

tends upwardly, being formed wholly from the The upper side of the plate A '5 tom of these creases the usual nail-holes, f f, are

punched.

This improved shoe possesses the followiug characteristic advantages: The grain of the metal extending longitudinally of the shoe renders the sides-or legs where they are not strengthened by the projecting calks as strong as possible for their weight, and the grain, by extending in parallel and substantially straight direction, is under no strain, as in those shoes where the fiber of the metal is distorted or disturbed by bending or other violent manip- For the same reason the respective iron and steel portions are not liable to sepa rate, as in a bent shoe, thus avoiding the slivering of the outer layers or portions.

only part that might otherwise be weak by reason of the grain of the metal extending transversely to it. The outer flanks of iron afford a soft and malleable substance in which to form the creases and punch the nail-holes, it being impracticable to punch these through the steel portion of the shoe. The iron center affords a ductile substance from which to 8 strike up or swage the toe-clip, and the clip formed thus of iron is less brittle than if of steel, and the iron center also, by extending through the toe-calk, renders the middle portion thereof softer than the ends, which are of sult graphically, the dotted line at w denoting 5 the outline of the toe-calk after having been subjected to a certain amount of wear.

This shoe is made as follows: An ingot is first built up of two steel cores separated by and enveloped by bars or plates of wroughtroo iron. This is heated and rolled down until a flat plate or bar is made of a width The toe- 7 5 calk, by being made to extend across the greater portion of the toe of the shoe, strengthens the somewhat greater than that of the finished shoe and as thick as the shoe is through its calks. This bar is then passed while hot between special rolls, which reduce it at once to the thickness of the plate A between the calks, leaving thecalks standing. These operations are fully described in my application executed this day for patent on improvements in bars of combined iron and steel and their manufacture, application N 0. 150,778, filed December 19, 1884. The same operation also forms the concaves in the upper side of the bar. The shoes are next punched out of this bar, following one another heel to toe, the shoe-blanks thus formed having each the same outline as the finished shoe, except that their heels are wider apart, and their toe has aslight projection to form the toeclip. The heels of each shoe are then squeezed together against a former. The creases are then formed and the toe-clip is then struck up by a swaging-roller. All these operations are described in my application for patent executed this day entitled improvements in the manufacture of horseshoes with solid calks, application No. 150,889, filed December 20, 1884, and the three operations last named are best performed by the machine disclosed in my application for patent on improvements in horseshoe machines, application No. 151,134, filed December 26, 1884. Finally,

, the nail-holes are punched,-preferably one at a time, by a punching-press.

The modified shoe shown in Figs. 5 and 6 is whatis known as a flat shoe, being nearly devoid of calks, or, more correctly, being formed with extremely low calks. The calks B and C O are beveled off gradually on their rear sides and have an abrupt front side, thereby render ng the toe of the shoe enough thicker than the remaining portions to prevent its wearing off before the shoe is otherwise worn out. The toe will be prevented from wearing away faster at the sides than in the middle, and thereby acquiring a rocker form by the iron center, the steel sides remaining sharp after the center has worn down below them. In this shoe the grain of the metal extends quite straight through the heel portion, as shown, instead of curving inwardly. Thisis d=uetotheshoebeingstamped out originally of the exact outline desired, thereby avoiding the pressing of the heels together; but the former method is preferable.

My invention may be in part availed of in making a shoe of all iron or all steel; but the shoe made of the combined metals, as described, is preferable.

What I claim, anddesire to secured by Letters Patent, is

1. A horseshoe of wrought metal, wherein the grain of the metal extends in parallel and substantially straight direction longitudinally of the shoe, substantially as specified.

2. A horseshoe of wrought metal, wherein the grain of the metal extends in parallel direction,crossing the toe portion thereof longitudinally of the shoe, and extending through the heel portions thereof with a slight inward deflection substantially parallel with the outlines of the heel portions,.as specified.

8. A horseshoe of wrought metal, wherein the grain of the metal extends in parallel directionlongitudinally of the shoe, and crossing the toe portion thereof transversely to its outline, and provided with a toe-calk extending across its toe portion transversely to the grain of the metal, thereby strengthening the toeportion, substantially as set forth.

4. A horseshoe of alternate strips of iron and steel, wherein the grain of the metal extends in substantially parallel direction longitudinally of the shoe, and calk projections are formed in the steel portions of the shoe, substantially as set forth.

5. Ahorseshoe of combined iron and steel, wherein the grain of the metal extends in parallel direction longitudinally of the shoe, the middle of the toe portion of the shoe being of iron, and the toe-clip being formed from such iron middle, substantially as set forth.

6. A horseshoe of wrought metal having a toecalk of combined iron and steel, the ends of the calk being of steel and its middle of iron, whereby the middle wears away faster in use than the ends, substantially as set forth.

7. A horseshoe of combined iron and steel, wherein the grain of the metal extends in parallel direction longitudinally of the shoe,crossing the toe portion transversely to the outline thereof, having steel sides and iron flanks,

whereby the creases and nail-holes are formed witnesses. v
